ICE EFFECTS
ON STREAMFLOW -- During cold weather, ice effects on stage and
discharge determinations at some streamgages are likely. Streamgages
experiencing ice conditions will have the discharge record temporarily
disabled to prevent the display of erroneous discharge values. The
discharge record will resume when it is determined that ice conditions
are no longer present. Adjustment of data for ice effects can only be
done after detailed analysis.
